BACKGROUND ART

In general, in a sink installed in a bathroom or a toilet, a sink 1′ that can receive and use a predetermined amount of water, a water supply device that supplies water to the sink, and a drain device that stores water at the sink or that discharges the stored water are installed, and a user stores a predetermined amount of water at the sink, uses the water for washing a face, and discharges the water through the drain device after using the water.

As described above, a common drain device used in the sink stores water at the sink or discharges the stored water to a drainpipe while being opened and closed, and in the common drain device, a drain body that forms a drain in a state penetrated in a lower portion of the sink and a pressing opening and closing device installed at the inside of the drain body and that opens and closes the drain while vertically moving are installed, and in such a drain device, an automatic popup device that operates with a pressing button method or a passive popup device that operates with a lever method is commonly installed and used.

The drain body has a drain in a vertically standing cylinder-shaped pipe shape, and at an outer circumferential surface of an upper end portion, a latch jaw is protruded, and the drain body fastened to vertically penetrate to a lower portion of a sink is stably latched and fastened, and in a lower portion of the drain body, a common fixing nut and drainpipe are coupled with a screw fastening method, and at each of lateral both sides of an intermediate portion of the drain body, drain holes are bored, and the drain hole communicates with an overflow passage installed in a bottom portion of the sink, and water overflowed through an overflow hole bored in an upper portion of the sink is discharged to the outside through a drainpipe while being injected into the drain hole via the overflow passage.

As an example of such a popup device, Korean Registered Utility Model No. 20-0441759 discloses a popup device in which a drain stopper is conveniently opened and closed and that thus provides convenience to a user.

The popup device has a merit that can easily open and close a stopper through a pressing opening closing device, but uses a method of fastening a drainpipe and a drain trap through a fixing nut, and such a coupling method has a problem that a construction work is complicated and replacement and repair works are difficult.

For example, when installing the popup device in a sink, space between a wall in which the sink is installed and the drainpipe is narrow and thus a tool for tightening a fixing nut cannot enter into the space and thus the popup device is first coupled to the sink and installs the sink in the wall.

Recently, in order to prevent exposure of a drain trap located in a lower portion of the sink and to enhance an interior decoration effect, a construction of various shapes has been installed.

However, when the popup device is blocked by hairs or foreign substances or when it is necessary to replace the popup device due to damage of a product, in order to release the fixing nut, when first disassembling the construction, there is a problem that the popup device can be replaced or repaired and that the disassembled construction is damaged, and thus there is a problem that a worker is exposed to a safety accident, and even in a sink in which such a construction is not installed, it is difficult to insert a tool for releasing the fixing nut due to small space, and thus there is a problem that it is necessary to request a support to a repairman.

DETAILED DESCRIPTION OF INVENTION Technical Problem

When installing an automatic popup device having a pressing opening and closing device in a sink, it is difficult to perform a work that fixes or releases a fixing nut that fixes a popup device and a drain trap and thus the present invention has been made to solve a problem that a construction, replacement, foreign material removal, or washing work is difficult.

For a better understanding of characteristics of the present invention, hereinafter, a popup device for a sink according to an exemplary embodiment of the present invention will be described in detail.

The present invention relates to an installation structure of a popup device for a sink and a method of installing the same. The installation structure of a popup device 10 for a sink, installed in a sink 1 and having a latch jaw 13 close contacting with a drain hole 2 formed in the sink in an upper end portion and having a drainpipe 11 having a drain space portion 14 laterally bored at each of both sides of the left side and the right side of an intermediate portion and that communicates with an overflow passage 4 installed at a bottom surface of the sink and in which a sewer pipe 7 fastened to a drain trap 8 installed in a lower portion of the sink is coupled in a lower portion includes: a close contact member 20 including a close contact portion 21 inserted and coupled to close contact with the lower end of the latch jaw 13 and formed in a diameter corresponding to the latch jaw, an extension portion 22 extended to a diameter corresponding to a drain hole from a bottom surface of the close contact portion, and corrugations 23 for blocking water leakage at an outer circumferential surface of the lower end of the extension portion; and a sealing member 30 inserted and coupled to a lower portion of the drainpipe 11 and formed in a diameter corresponding to the drainpipe and having a plurality of corrugations 31 at an outer circumferential surface, wherein the close contact member 20 is inserted and coupled to close contact with the lower end of the latch jaw 13, and in a state in which the sealing member 30 is inserted and coupled to a lower portion of the drainpipe 11, the sealing member is forcedly inserted into the drain hole 2.

The popup device 10 is formed with a drainpipe 11 having a stopper 12 for opening or closing the drain hole 2 formed in the sink 1 and a sewer pipe 7 screw-coupled to the drainpipe.

In the drainpipe 11, a pressing opening and closing device 15 screw-coupled to the stopper 12 is installed within the drainpipe 11, and in an upper end portion thereof, the latch jaw 13 is formed, and at each of lateral both sides of an intermediate portion thereof, a laterally bored drain space portion 14 is formed, and at an inner circumferential surface of a lower portion thereof, a screw thread (not shown) for screw-coupling to a sewer pipe is formed.

The drain space portion 14 communicates with the overflow passage 4 installed in a bottom portion of the sink, and the sewer pipe 7 is fastened to a drain trap (not shown) installed in a lower portion of the sink.

One side of the drain trap is fastened to the sewer pipe and the other side thereof is installed to penetrate a bottom surface, and the drain trap has a corrugated pipe that can adjust a length to correspond to a spot situation and is generally a drain trap to be used at a spot.

As the pressing opening and closing device 15 moves upward or downward a stopper screw-coupled to an upper portion through a pressing operation, the pressing opening and closing device 15 performs a function of opening and closing the drain hole formed in the sink, and an automatic popup device of the pressing opening and closing device is already well known and thus a detailed description of a well-known configuration and operating method will be omitted.

A close contact member according to an example embodiment of the present invention will be described with reference to FIG. 6.

The close contact member 20 is inserted and coupled to close contact with the lower end of the latch jaw 13, and when the popup device 10 is inserted into the drain hole 2, the close contact member 20 blocks the drain hole to perform a function of preventing water from being leaked between the latch jaw and the drain hole.

The close contact member 20 includes a close contact portion 21 inserted and coupled to close contact with the lower end of the latch jaw and having a diameter corresponding to the latch jaw, an extension portion 22 extended in a diameter corresponding to a drain hole from the bottom of the close contact portion, and corrugations 23 for blocking water leakage at an outer circumferential surface of the lower end of the extension portion.

Further, when the close contact member 20 is inserted and coupled to the drainpipe, in order not to block a drain space portion formed in the drainpipe, it is preferable that a length of the extension portion is formed to correspond thereto.

The corrugations 23 formed in the close contact member performs a function of blocking the inside of the drain hole so as to prevent leaked water from dropping to a gap between the latch jaw 13 and the drain hole 2, and in order to insert the corrugations 23 into the drain hole, it is preferable that the corrugations are formed in a diameter smaller than that of the close contact portion.

The sealing member 30 is formed in a diameter corresponding to the drainpipe 11, is inserted and coupled to the drainpipe, and is coupled to locate at a lower portion of the drain space portion 14, and in a state in which the sewer pipe 7 and the drainpipe 11 are coupled, in order to easily forcedly insert the sealing member 30 into the drain hole or to easily take out the sealing member 30 from the drain hole, a plurality of corrugations 31 are formed at an outer circumferential surface.

Referring to FIGS. 2 and 3, conventionally, in order to securely fix a popup device 10′ to the sink, a separate fixing nut 5′ is necessary, and a tool for fastening the fixing nut 5′ is necessary, but in the present invention, a plurality of corrugations formed in a sealing member securely fix a drainpipe within the drain hole and thus there is a merit that a worker can perform a construction work without a separate tool or flange, and a processing work that forms a screw thread at an outer circumferential surface of a drainpipe 12′ so as to insert a fixing nut may be omitted.

In order to easily insert the close contact member 20 and the sealing member 30 into the drainpipe or in order to easily separate the close contact member 20 and the sealing member 30 from the drainpipe, the close contact member 20 and the sealing member 30 may be made of a material such as rubber or silicon having excellent elasticity, and a material of the close contact member and the sealing member is not limited to the above materials.

Referring to FIGS. 8 and 9, the close contact member 20 and the sealing member 30 according to an exemplary embodiment of the present invention are integrally formed together with a connection portion 40 disposed therebetween, and when the close contact member 20 and the sealing member 30 are integrally formed together with the connection portion 40, it is preferable that a drain groove 41 is formed at a location corresponding to the drain space portion 14.

In general, water filled in the sink is injected into the drain space portion 14 by moving along the overflow passage 4, and when the drain groove 41 is not formed in the connection portion, water, having passed through the drain hole is not discharged to the drain space portion and is stagnated at the overflow passage and thus a phenomenon that bad smell occurs and that water flows backward may occur.

Hereinafter, a method of installing a popup device for a sink according to an exemplary embodiment of the present invention having the foregoing configuration will be described.
